EDELWEISS - Rocklight II 9.8mm x 50m Rope - Anthracite

The EDELWEISS Rocklight II is designed specifically for sport climbing due to its optimal balance of weight and performance. With a diameter of 9.8mm, it provides the necessary strength while being lightweight at just 61 g/m. This makes it easier to handle and carry, which is crucial when climbing long routes. Its construction from durable polyamide ensures it can withstand the rigors of repeated use, while its impact force and UIAA falls ratings confirm its reliability in dynamic climbing scenarios.

The impact force rating of 8.5 kN for the Rocklight II indicates how much force is transmitted to the climber and anchors during a fall. A lower impact force generally means a softer catch, which can be more comfortable for the climber and less stressful on the gear. This rating makes the Rocklight II a good choice for sport climbing where falls are more frequent, as it helps reduce the risk of injury and equipment strain.

The Rocklight II is not UIAA Water Repellent certified, which means it may absorb water more readily than treated ropes. In wet conditions, this can lead to increased weight and reduced performance, as wet ropes are more prone to slipping and can become less manageable. For climbing in consistently wet environments, a water-repellent rope might be a better choice to maintain performance and safety.

The Rocklight II has a sheath slippage rating of 0 mm, indicating that the sheath is tightly woven and won't slip over the core. This is a critical feature for durability, as sheath slippage can lead to uneven wear and potential rope failure. A stable sheath ensures that the rope maintains its integrity over time, even with frequent use in demanding climbing situations.

The 9.8mm diameter of the Rocklight II strikes a balance between manageability and strength, making it ideal for sport climbing. Thinner ropes are generally lighter and easier to handle, which is beneficial for long climbs where weight savings are important. However, they must also be strong enough to withstand falls. The 9.8mm diameter offers sufficient durability while remaining easy to clip and manage during climbs.

The static elongation of 10% for the Rocklight II indicates how much the rope will stretch under a static load. This is an important factor when considering the rope for top-roping or hauling, as excessive stretch can lead to increased movement and less control. A 10% elongation provides a good balance, allowing for some give without compromising control or safety during climbs.

With a first fall elongation of 32%, the Rocklight II provides a soft catch during the initial fall. This is beneficial for reducing the impact on the climber and the gear, making it a safer option for sport climbing where falls are common. However, climbers should be aware that this elongation means the rope will stretch significantly during a fall, which can affect positioning and control.

The 50-meter length of the Rocklight II is particularly beneficial for sport climbing routes that are shorter and do not require extended rope lengths. It allows climbers to tackle a wide range of climbs without the added bulk and weight of longer ropes. However, for multi-pitch climbs or routes that require rappelling, a longer rope might be necessary to ensure safety and reach.

The lightweight design of the Rocklight II, at 61 g/m, offers significant advantages in terms of ease of handling and reduced fatigue during climbs. However, the trade-off is that lighter ropes can sometimes be less durable over time, especially if used frequently on rough surfaces or in harsh conditions. Climbers should consider their specific needs and climbing environments when choosing a rope to ensure it aligns with their durability requirements.

The Rocklight II is rated for 6 UIAA falls, which indicates its capacity to withstand multiple severe falls. This rating is competitive for a rope of its diameter and weight, making it a reliable choice for sport climbers who frequently push their limits. While some ropes may offer higher fall ratings, the Rocklight II balances performance and affordability, making it a practical option for many climbers.
